AbstractMobile IT-devices (Smartphones, Tablet-PCs, etc.) are often used while performing other tasks in parallel, e.g. while walking. However, mobile device and environment often compete for the users’ attention. Binding too much attention on the mobile device will reduce attention on the environment. Especially in risky environments like road traffic, this might trigger substantial danger for users and third parties. Therefore, graphic user interfaces (GUIs) have to be adapted to it. Yet, lightweight mobile devices have small displays and only a limited number of objects can be displayed. Content with multiple subunits has to be arranged, e.g. by forming subcategories. Hierarchical structured menus facilitate this. In our survey, we compared the effect of different menu concepts on gaze behavior while walking. Menus containing 4–8 icons per level required the lowest number of gazes. In single interactions, the shortest visual distraction was found for the least number of objects on the screen.
